Abstract (en)
[origin: EP1961501A1] A method of manufacturing an electric resistance welding pipe is provided, in which a lateral edge shape is made to be an appropriate shape immediately before electric resistance welding is performed, thereby penetrators are securely removed during the electric resistance welding, consequently an electric resistance welding pipe having excellent characterization of welded seam can be obtained. A fin shape in finpass forming is printed to lateral edges of a strip, thereby the lateral edges of the strip are shaped with predetermined tapering.
